Coastal Erosion Control
Revetments
Revetments are a structure built to absorb and dissipate the energy of incoming waves, protecting the coast from erosion. Usually made of materials such as rocks, concrete and geotextile fabrics, revetments act as a buffer that reduces the impact of waves to preventing them from wearing away land. The most famous regional example of a revetment is the Johnson Rocks on St. Simons that were placed in the 60's to protect the shore. They still are a prominent feature of the island, and remain effective to this day after decades of use.
